I've heard from the folks at Pineboard[1] there's been some new activity, as this year manufacturing ramped back up... it's still decent hardware but is getting long in the tooth.
Regarding the Hailo featured in the article, a few of us have been messing with it on a Raspberry Pi 5[2], and it offers more performance in a similar power envelope. The major downside is availability. I can buy the Coral on many electronics supplier sites, but Hailo seems to be selling through 'Product inquiry' right now, which is not easy to navigate as an individual!
